the guessing game
In a conversation with Keith Craft I asked what was the hp loss for a Cobra. Keith said they saw typical a 20% loss. He dyno's his motors before they ship out. Sometimes he installs them into Cobra and then dyno's the Cobra.
Some of the CC members have dyno'ed their Cobras with different sidepipes and report losses of 40 to 100 hp.
I think Keith's experience is of value because he dyno'ed the same motor out of the car and installed.
I have hear loss numbers of 15% to 27% for a Cobra. But for most of us it's a guessing game. I had mine dyno'ed on a chassis dyno for rear wheel hp. I can only guess at the flywheel power.
Several of my buddies have motor that were dyno'ed before they were installed into their Cobras. They can only guess at their rear wheel hp.
